Spear Phishing Attack
-Hari V

2.
Phishing is a social engineering tactic where the attacker attempts to get a user to divulge sensitive
information (like username/password, bank account number, personal information, etc.) or go to a
malicious website where such information can be harvested. It uses "bait" such as telling the user that they
are their bank asking for the information or posing as some other authority like the system administrator.
Usually it is delivered by email or Instant Messenger.
Spear phishing is a subset of phishing. Whereas general phishing targets a wide range of people trying to
get some of them to divulge general information, spear phishing targets key individuals who are expected
to have very special access or information that the attacker wants. It could be a company executive or a
military officer. Spear phishing is an e-mail spoofing fraud attempt that targets a specific organization,
seeking unauthorized access to confidential data.
